[Mimedefang] Is there a way to change "To:" header?

[Jeff Rife]

Our users have MS Outlook as the e-mail client, so they can't match on 
abitrary headers.  There are some political issues with changing the 
subject on false positives, especially when it is then replied to and the 
original sender sees we think they are a SPAMmer.

So, my idea was to add an innocuous name to the "To:" header.  Since this 
is not used by sendmail to do any delivery (the envelope recipients are 
used instead), I think it is safe, and Outlook *can* filter on it.

The question is: how?

MIMEDefang exposes a global variable $Subject that makes adding to the 
subject easy, but I can't find anything similar for other headers.  I'm 
not a Perl guru, though, so I might have missed the setting in 
mimedefang.pl.
